THEMIS: Noachis Terra in false color

Noachis Terra in false color (THEMIS_IOTD_20190508)THEMIS Image of the Day, May 8, 2019. Today’s false color image shows part of Noachis Terra. The large craters are unnamed, as is the channel in the center of the image. Dark blue tones in this false color image indicate basaltic sands.

The THEMIS VIS camera contains 5 filters. The data from different filters can be combined in multiple ways to create a false color image. These false color images may reveal subtle variations of the surface not easily identified in a single band image.

InSight’s dusty selfie

PIA23203_main_slider_after-16This is NASA InSight’s second full selfie on Mars. Since taking its first selfie, the lander has removed its heat probe and seismometer from its deck, placing them on the Martian surface; a thin coating of dust now covers the spacecraft as well.

This selfie is a mosaic made up of 14 images taken on March 15 and April 11 – the 106th and 133rd Martian days, or sols, of the mission – by InSight’s Instrument Deployment Camera, located on its robotic arm.

InSight’s first selfie showed its instruments still on the deck. Now that they’re removed, the viewer can see the spacecraft’s air pressure sensor (white object in center), the tether box for its seismometer and the tether for its heat probe running across the deck. Also visible is its robotic arm and grapple. [More at link]

Mars 2020 can now phone home

PIA23193Mars 2020 engineers and technicians prepare the high-gain antenna for installation on the rover’s equipment deck. The antenna is articulated so it can point itself directly at Earth to uplink or downlink data.

The image was taken on April 19, 2019, in the Spacecraft Assembly Facility’s High Bay 1 clean room at NASA’s Jet Propulsion Laboratory, in Pasadena, California… [More at link]

Curiosity update: Go SAM, go!

FRB_610103177EDR_F0751398FHAZ00341M_-br2Sols 2397-99, May 3, 2019, update by MSL scientist Kristen Bennett: The first round of SAM experiments was successful, so in the weekend plan we get to move forward with the GCMS (Gas Chromatograph Mass Spectrometer) experiment. First, additional sample will be delivered to SAM. Then the sample will be heated and analyzed. This is exciting because we decided to drill the Kilmarie target after the Aberlady drill hole did not yield enough material for us to be confident that there would be enough sample for SAM. With the first SAM experiment complete and the second experiment in the weekend plan, things are looking good so far at the Kilmarie drill hole.

In addition to the SAM experiment, ChemCam is going to be busy this weekend. ChemCam will target “River Spey,” a light-toned vein near the drill hole, and “Rothes,” a small block that exhibits laminations. Finally, ChemCam will re-target “Tiffany.” Tiffany is a pebble that was targeted earlier this week, but we missed by a little bit because it is such a small target. Since we are sitting in the same location for a while during the drill campaign, ChemCam has the opportunity to redo this observation, now called “Tiffany 2.” Mastcam will take documentation images of each of the ChemCam targets… [More at link]
